11 claims. (ci. 16-7) This invention relates to carpet anchor means and particularly of a type designed to firmly secure the iloor covering at wall edges, across doors, hearths or other,

sills and abutments where the abutting surfaces are threeeighths of an inch or more above the iioor level.

Due to the positioning of the attaching means adjacent an abutting edge the use of the conventional attaching means present many installation and replacement problems. Unsightly bulging or crimping of the carpet was a common fault through the use of these earlier constructions as well as the resultant marring of the flooring or tearing of the carpet through the use of nails, staples, screws or other faulty securing means. Y

It has also been found that due to the uncvenness of oors, a void or space between the carpet and/or fastener with theoor which resulted in a catch-all for dust and dirt at these locations. These conditions were found to be increased where an under padding was used between the carpet and floor. In many instances where an adhesive had been used in direct contact with the carpet or inadequate carpet securing means, the oor covering would follow the valleys or oor contours with the resultant irregularities and generally unsightly appearance, particularly at the junction with another abutting surface.

It is an object of my invention to provide carpet anchoring means or edging to be applied to floor surfaces where the oor covering terminates at an edge, sill orabutment of a height an appreciable distance above that above the oor level and still present, after installation, a at even and finished oor covering `and anchor trim.

Another object is to provide a carpet anchor trim which may be efficiently and rapidly applied to oor surfaces as well as being readily removed when replacement of the worn covering occurs.

A further object is to provide an anchor trim that may readily be secured to surfaces other than wooden flooring.

Still another object is to provide carpet anchoring means that may be installed without nails, screws, tacks or staples.

Another and further object is to provide carpet anchoring trim which enables the positive use of an adhesive to create a key lock between the floor surface and'carpet anchoring means.

Other and further objects of the invention will become apparent from a consideration of the following detailed description thereof, and of one form of theapparatus which may be employed to practice the invention as`illustrated in the accompanying drawings in which: v

Figure 1 is a perspective view of my improved wall strip carpet anchoring construction.

Figure 2 is a similar view in reverse position to show the bottom construction of the anchoring means.

Figure 3 is a fragmentary cross-sectional View showing the application of my wall strip carpet anchoring means.

Figure 4 is a cross-sectional view showing amoditication disclosing the combination of my wall strip carpet anchoring device with a carpet saddle.

Figure 5 is an enlarged fragmentary sectional view showing one of the hook-like prongs in engagement with the rings of the carpet.

In the drawings where like reference characters 'denote like parts, the numeral 10 indicates the top surface of an approximate U-shaped construction while the lower section 12 is shown spaced from the upper surface by a front slanting wall 14. A double parallel row of spaced prongs or arcuate hook-shaped members 16 are shown, forced out of the metal, preferably of extruded aluminum alloy, creating openings 18 in the metal, these prongs curving inwardly and faced toward the front or closed edge of the anchoring device.

Parallel spaced slits or cut-out portions 20 are made in the lower section 12 forming approximately squared plates 22 spaced throughout the longitudinal length of the anchor. These sections remain integrally connected at their ends with the inwardly slanting or tapered front edge 145. A plurality of spaced small perforations 24 are made in the sections in the lower horizontal surface 12 for a purpose to be subsequently described. Larger spaced beveled openings or apertures 26 are also made in the top section lil. These openings 26 are provided for the reception of screws 32 as will be subsequently described to additionally secure the anchor to the floor. l have also provided a parallel double row of spaced prongs or hook-like members 16 for a purpose to be later explained. l v

In application, the floor surface immediately below the locations where the anchor strip is to be installed vis rst coated with the adhesive and the anchoring device positioned directly thereupon. s n

The Vanchor strip is placed in position with the forward or closed edge 14 spaced a sucient distance short of the wall 30 as shown in thisview of the particular abutment so as to provide an adequate gully 28 of `sufcient Width. As explained above, the adhesive will contact the perforated' areas 22 and will seep into these openingsV and also spread and run well into the slits 20 and create a key lock ateach of these locations between the `iiooring and the anchor trim.

Additional anchor fastening or Isecuring means is provided by insertion of screws or nails 32l into the beveled apcrtures26 and the oppositely opposed openings 34 in the bottom sections. 'The screws32 are adaptedto be screwed through the openings 26 and 34 in the VU-shaped anchor trim and then into the ooring to additionally insure a firm attachment of the anchor to the flooring, the head being countersunk so as to leave a smooth surface at these locations over which the carpeting is to be appiied. This construction providesl a complete and adequate trim anchoring means topreclude movement or dislodgement of the anchor trim and carpet 'and yet enable rapid installation and speedy replacement.

As previously explained, the adhesive will seep through the openings in the separated plate sections as well as in the slits or spaces therebetween and when'dry will firmly and securely key lockthe anchor strip. The addition of the screw through the anchor device near the front edge aids materially in strengthening the structure at thisforward location. s

In application,l after the adhesive has yset and the screws installed, the padding 36 isplaced in`abutting Yposition against vthe rear or open edge of the strip. Thel carpet 38, previously cu't, is brought up parallel to the anchor ledge, under pressure, over the under padding and top surface l0 until the hook-like prongs engage the warp of the carpet to firmly secure the longitudinal edge against subsequent dislodgement. The end 40 is then forcedor compressed within the gulley 2 8 and becauseof the pointed top forward edge of the anchor restricting the longitudinal opening the ends whenV forced into this restrictedfgulley will be retained within.'v vIn addition, although this'parti'cular portion of the carpetr is forced along the entire length into 3 the gulley, a right angular effect is obtained due to the nap of the carpet extending rather fully above the junction and by so doing completely obliterates or covers the opening along the entire length.

Itis to be observed that the slits in the lower section 12 have an additional value in that in cutting the trim to span a definite width it becomes necessary for the Workman to cut a section while on the job. Due to this lower section being previously cut the subsequent cutting of the upper surface is expedited. The flexibility of this construction adds greatly to the installation of the anchor trims and .also constitutes a saving of time.

In Figure 4 I have provided a carpet saddle 42 to be used in combination with the anchor edging shown above. This saddle member is formed by two angularly disposed converging surfaces 44 and 46 to establish an obtuse angle therebetween. After the adhesive used in installing the anchor has set and the carpeting 38 has been laid and pulled up for engagement with similar row of hooks 52 and the carpet end 54 forced or compressed into the gulley 56, the carpet saddle 42 is then placed over the covering at this location with the forward edge also extending down into the gulley 56. In the event the saddle is to be used differently, as to just provide a finished edge for a carpet, this edge will merely extend down into contact with the fioor.

A beveled opening 58 is provided in the rear portion 44 of this saddle for the reception of a screw 60 longer than the one used in Figure 3, which will be countersunk in the plate section 44, passing through the carpet, the apertures 26 and 34 of the anchor and well into the iiooring to firmly secure the combined structures. It is obvious that the anchor trim is previously secured as in the form shown in the Figures l to 3. This construction also acts as a bridge for the space adjacent the carpet end and also serves to additionally provide a gully concealing means and further reduces the collection of dust along this strip.

This saddle strip 42 is also used to provide a durableV edging at locations such as freight entrances, elevator entrances and other places where there is an excessive and heavy amount of traffic.

Although the screw 60 in Figure 4 is shown extending through the lower surface 12 into the floor it is conceivable that a shorter screw can be used so as to stop short of this surface 12 and still adequately support the protective plate at the end of the carpet.

The enlarged sectional view shown in Figure S more accurately defines the hook-like prongs 116 forced out of the metal of strip 11.

Although I have described the illustrated embodiments of my invention in considerable detail, it will be understood by those skilled in the art that modifications and variations may be made without departing from the spirit of my invention. The various forms may be modified or changed to meet conditions, but basically the subject disclosure only broadly reflects this development. I do not, therefore, wish to be limited to the specific embodiments of my invention shown and described herein, but claim as my invention all modifications coming within the scope and purview of the appended claims.
